Is it possible to run the Robot Commander app and a program on the EV3 brick at the same time?
If so how would it be accomplished?
No, the Robot Commander app downloads and runs a program on your EV3. If you already have a program running, it will be stopped and the program downloaded by the commander app will run instead.
I have been trying for the past couples days to make that work, but I cannot figure it out so I would say no.
